Description

一种多金属混杂C/C复合材料
技术领域
本发明涉及一种复合材料，特别是涉及一种多金属混杂C/C复合材料。
背景技术
众说周知C/C复合材料高温性能非常优异，在飞机发动机，刹车盘，结构受力件等领域具有广泛的应用，然而由于其脆性大，易碎裂，导热性能高，大大限制了其使用范围。而难熔金属强度高，韧性高，其断裂的临界缺陷远高于碳化硅陶瓷，由于金属原子的长程有序排列和原子间金属键的特性，使其具有一定的塑性。树脂基复合材料其缺口敏感性低，断裂韧性好，导热性能极低，且易于加工成型。若将C/C材料、不同金属合金薄板以及树脂基复合材料通过热压成型，制备出一种多金属混杂C/C复合材料，使的该材料具备优异的力学性能，综合了传统纤维复合材料和金属材料以及树脂基复合材料的特点，弥补了单一材料的不足，不但具有高比刚度和比强度，优良的疲劳性能以及损伤容限性能，还具有金属材料的韧性和可加工性，将显著提高材料的强韧性，大大降低材料的缺口敏感性，使其成为航空航天飞行器结构所需材料的理想选择。
一直以来，金属相增强陶瓷材料由于其优异的性能，各自的优缺点互补，一直是研究热点。文献“金属间化合物/陶瓷基复合材料发展现状与趋势，刘凡，何柏林.粉末冶金材料科学与工程，2007，12(1)：8-12”揭示了金属间化合物增强陶瓷材料的现状，其中沈建兴等人介绍了一种镍铝合金增强氧化铝陶瓷材料，研究表明Ni3-Al对Al2O3陶瓷有明显的增韧作用。所得复合材料的抗弯强度与断裂韧性从室温至600℃范围内，随温度升高下降很少。但随着材料的进一步升高，由于金属材料的蠕变性能，使得材料的整体性能下降。张炳荣等人通过粉末冶金的方法制得,与纯Al2O3陶瓷相比，该复合材料直到1000℃仍保持了较高的断裂韧性。高明霞等人采用自发熔化渗透法制备了高TiC含量的NiAl/TiC和Ni3-Al/TiC复合材料，使材料的断裂韧性大大增加。可见这类材料通过各自的优点而弥补或部分弥补了彼此的缺点 , 具有优异的性能。然而此类材料中空隙难以完全消除，若加入过多烧结助剂势必影响材料的力学性能，特别是通过自发熔化渗透法制备出的材料，结构不均匀，且存在不能消除的气孔，大大降低了材料的断裂韧性。
文献“申请号为201410426478.0的中国专利” 公开了一种碳纤维增强聚酰亚胺基体纤维金属层板制备方法，发明方法制备出的碳纤维增强聚酰亚胺基体纤维金属层板，具有优良的耐疲劳特性，并且成本远低于碳纤维增强的复合材料，并具有耐腐蚀、阻燃、耐冲击等有点，能够广泛应用与航空航天领域。但是该材料强度小硬度低，从而限制了其使用领域。而一种综合了传统纤维复合材料，金属合金材料以及树脂基复合材料特点的多层复合材料，将具有更加广阔的应用前景。
